T all whom it may concern.

Be it known that l, Uranus Sonsnsnrc a citizen of the United' States ofVAmericas residing at Berwyn, in the county of Custer and State ofNebraska, have invented certain new and useful Trnproveinents inGovernors for Tractors, of which the following is a specification.

This invention relates to governors for tractors and more particularlyto an auto- .matic governor for the well known Ferdaccordance with theinventiong and is a perspective View showing a connection between theusual oscillatory throttle controlling' rod or a Fordson tractor and acrank arm carried by the throttle valve stein of such tractor and'showing in vaddition means `for connecting the governor to the crank armon the throttle valve stein.

designates the cylinder head and 6 designates Va part of a radiatorshell of a well known Fordson tractoru A bearing block 7 is secured bybolts or rivets 8 to the shel'l 6 whilea plate 9 is ecured by seine ofthe cylinder head cap s -ews 10 in position to project laterally beyondthe cylinder head and to lie in a horizontal position., This latecarries a bearing ,11 which tege with the bearing "Z constitutes asupport A a rotative shaft 12, shaft 12 carries a drive pulley 13 overwhich a belt 14 passes. This belt is driven from the usual `Earl-fpulley15 and may be an extension of the -ian belt itself.

A sleeve 16 is mounted to slide upon shaft 12 and act against a thrustcollar 17 carrying anti-friction elements such as balls 18. Weights 19are pivoted at 20 Ito ears 21 of the pulley 13, and angnlarly extendingtails 22 of said weights act against the end of the sleeve to thrustsaid sleeve to- Ward the left when the weights move outwardlyundercentrifugal force. This action is against the tension of a spring 2a,

Thearm 26 oi lever 27 is forked and the arms of said fork lie vbe tween thecollar 1T and the collar 25 and embrace the shaft 12 it being noted thatsaid collar and washer are spaced apart distance considerably greaterthan the thickness or arm 26 softhst the fork may nieve toward the leftindependently or' these parte. The opposite end ofthe spring 2li bearsagainst a collar 29 that may be justed lengthwise oit the shaft 12 bymeans of set screw Adjustment of this collar regulates the rate of speedat which the engine will run; finer adjustments may secured bymanipulation o'f thumb nut 3l which is threaded upon a screw to whoneend of a spring- 33 is connected. other end ci this spring is connectedat c; to a long erin 35 of lever 27. .llhe screw il@ formed uponconnected to the 3e at and o: aceite end of lint; is turneri and passesthrough an extension pla 9) wineAL is in turny secured by a screw i0 tothe usual crank Ll1 on the valve stein of the carburetor 1137 it being"understood that a turn'- ingmotion of this stem in one direction or theother serves to open or close the throttle valve ot the carhureter. Abearing bracket is secured by one of the cap screws 1G oft the cylinderhead in posi on to project laterally beyond the cylinder' head for oneend of a rod 45. IThis rod carries a crank extension or olre 46 an armla? of which projects through the cranlr extension 41 bureter.

This constructs uaiiy controllable 1r.

valve, 3 may be idle c w may be caused to run at any ues' of speedindependertly of, the action of governor, the capability of movement etthc arm 26, independently of collar 17., permitting the manual actuationof crank` al. to rotate stern 12.

By reason of the great length of the arm 35 in comparison with thelength oic the arxn 26 the governor is rendered extremely sensitive.`The parts are so correlated and arranged that the device isdn thenature of. an attachment adapt 'to be easily :ad quickly applied to feoout an change in the ,present construction ther-eo The governor 1sautomatlc and self contained,;1s of a simple7 practicai and durabledesign and is extremely sensitive to all variations in the load carriedby the tractor whether the engine is doing tractor or belt Work. y Y

Having described my inventionl` what I claim is:

The combination with a carbureter having :i rotative throttle valve anda crank on the stem of seid valve, of a manually operable rotative rod:md a crank 'thereon engaging the first named crank, an extension uponthe crank of the throttle valve stem, a lml: connected to seidextension, an L shaped lever comprising a long arm and a short arm, saidlever being pivoted I at its heel the movement of said lever whenmanually operated being against the tension of said' spring.

In testimony whereof I aix my signtu' in the presence of two Witnesses.
